MROVEWNT EN PAPER-FEEDING- MAGHINES.

The Schedule referred to in these Letten! Patent and part of the sama.

To fall whom if: lmay concern:

Bc -it' known that I, Wmson MovvnY,.of Minneapolis, in the county cf Hennepin, and in the State of, Minnesota, hate'. invented certainfnew and useful Improvements in. Machine for Feeding Paper to Cylinder Presses; and de hereby declare that the following is a full, clear, and exact description thereof', reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in the construction and general arrangement of a machine for feedingrpaper tol cylinder printing-presses, which, at each revolution, leaves one sheet ofpaper at the right time and place forY the grippers on the press to grasp/it and take it around the cylinder for printing. ,y

In order to enable others skilled in the artto which my -inveution appertains, to make and use the same, I will now proceed to describe its wustl-notion and operation, referring to the annexed. drawings, which form a part of this specification, and in which- .z 1-Figure 1 is a side view of the machine;

' Figure 2, a side view in section of the upper part thereof. l

Figure 3, a plan view of the fountain;

Figure 4, a side section of the same Figure 5, a plan view of the device for regulating the fall of the fountain;

Figure 6, a rear view of the table and arrangement for raising theV same; and

Iigure 7 is a -plan view of the movable joint which connects the rear lever with the upper connecting-rod.

A' represents a frame, made of suitable dimensions and material, arranged and placed in sucha manner that the front end of Van inclined 'stationary table, in

the upper part thereof, is just above the highest point.

of the cylinder B of a printing-press. The paper will be delivered on-this stationary table in a. manner hereinafter to be described, so that the n ippers or gripers of the press will grasp it and carry it around the cylinder, dispensing with the hands usually employed to feed such printing-presses.

Motion is communicated to my .machine by means of a crank, `(Lattached to theshaft of the' cylinder B,'

aA rod, D, connecting said crank with an upright lever, E, which is pivoted, at its lower end, tothe'lower rear part of the frame a.

The upper end ofthe lever E is slotted, and vjoined to an upper connecting-rod, G, by means of theI L-sbaped joint, F, g. 7.I

rllhis joint is fastened to the slotted end of the lever E by a screw-bolt and screw, or other suitable means, passing through the slot in such a manner that said joint can be raised or lowered in said slot, and secured at any point desired in the same, for a purpose hereinafter to be set forth. Y

The upper connecting-rod Gis secured, at its front end, to another upright lever, H, which is pivoted to v the lower part of the frame A, at a suitable distance from the lever E, the upper end of said lever H being also vertically slotted, as shown in fig. 1.

On each side of the upper part of the machine, and above the level ofthe inclinedstationary table, is au inclined slotted way or bar, I, the slot not extending to the ends thereof. vThe rear ends of said ways I I are groovcd on their inner side, 'om the end of the slot to the end of the bar. l

In the slots and grooves on the Waysy I I, thus described, a frame, J, slides back and forth, in the front end of which frame a roller, K, is placed, the shaft a of said roller having its bearings in the sides of said frame. l'lhe ends of the shaft extend through the slots on the Ways or bars I I, and one of them through the slot on the lever H.

Each vend of this shaft is provided with a pinion, L, which works on aninclined ratchet-bar, M, placed one on each side of the frame A, below but parallel with the s lot on the bars I, and Aone of them between said `bar and the lever H.

It will be seen that the motion communicated by the cylinder B moves the frame .Land rolle'l` K back and forth through the slots and grooves on the inclined ways I I.

On the frame J, a suitable distance in rear of the roller K, is secured a spring, N, on which rests another frame, O, which is hinged tothe rear end of the frame J, and in the ont end of which a fountain, P, is secured.

The fountain P is provided, on its upper side, with a hole, through which it is filled, and on its under side with a gate, through which some fibrous substance is placed, and the gate pressed or forced against this fibrous substance by screws, for the purpose of gradu- 'ling the flow of the liquid with which. the fountain is On the rear part of the frame J is placed a standard, R, on which a lever, S, is pivoted, said lever being connected, at its front end, with the frame O, and provided, at its rear end, with a weight, T, which serves, in ccnjunction with the spring N, to balance the fountain P, so that the brous substance in its bottom wilI not touch the roller K except when pressed down.

0n the upper side of the ways or bars I I, near the rear end, is secured a standard, U, which, on its upper side, is provided with-a slide, V.

This slide can be regulated so as to be placed at any point desired, by means of screws, b, and they are, near their frontends, provided with pawls or dogs W, which are pivoted on their inner. side, and strike against a bevelled bar, X, ou the frame O, when said .frame is moved towards the rear, causing the fibrous substance on the bottom of the fountain P to strike the roller K.

It will be seen that the point on the roller where this is done is regulated by the moving of the slides V V back or forth.

In the front end of the machine, under the stationary table, is pivoted a trame, which consists of two sidebars, d d, and a cross-bar, c.

These side-bars extend through to the rear end of the machine, resting on a cross-bar in the frame A,

. and between said side-bars d (l, immediately in rear of the stationary table, ispivoted a movable table, e, which rests on the same cross-bar in the rear end of the frame A, between the side-bars d d.

On this movable table the paper which is to be fed to the printing-press is placed.

.In the rear end of the frame A, a lever, f, is pivoted, the other end of which moves in asiotted bar, g, and a cord and weight, Il', is attached to'tbis end of said lever, which cord runs over a pulley, fi, as shown in 1i 6. gOn the lever f is a fulcrum, k, on which two bars, m and n, are pivotcd, one, m, operating outie adjustable a table e, and theother, fn, Yonrthe side-pieces d d fforY thebeing fibrous substance placed in. tlegate on its under side. A

The machine is then put in motion, and as the frame J' moves to the rear, up the inclinedplane, the dogs or rams W W strike the bevelled bars :v x, causing the fountain .P to strike the roller K, wetting the roller along its entire length.

When the roller is at its highest point, the weight h, operating on the table e, presses the paper against the wet line of the roller, and causes it to adhere to the saine, and as the roller moves toward the cylinder; the sheet of paper is taken up and rolled or wrapped around adjustable table e,

By changing -the position of the connecting-rod G,

the stroke of the frame O and roller K is.v shortened or lengthened, as may be desired .to suit the different.A

lengths or sizes of paper. point of delivery, but merely is picked up by the roller,

Having thus fully described my invention,

What I claim as new, and desire to secure by Lei?. ters Patent, is-

l. The combination ofthe reciprocating roller K. and fountain P, arranged in the frames J v and O, and operated by means of the pinions L L and racks M M, all substantially as and for the purposes herein set foith.

2. The fountain P, constructed as described, and' provided with some fibrousisubstance in its under side, and operated by means of vthe This does not change the the point where the paper cams `W W, 'so as to slightly wet the roller K at the proper place to allow this wet place to come in contact with the further margin of the paper, substantially as and for the purposes herein set forth.

3. The adjustable table e, hung'vou the adjustable iside-bars d d, and operated by the weight h, lever f,

and arms m and n,'substantially as and-forfthe purposesrherein set forth.

4. Thiadjustable connecting-rod G, secured to the lever E by means of the L-shaped joint F, for the purpose'ofshorteningor lengthening the stroke of the roller K, substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing, I have hereunto set my hand, this 18th day of July, 1868.
